BARC INTERVIEW EXPERIENCE 4

MY INTERVIEW

Sorry for the delay guys……

My Interview was on 7th julyChairman of the committee asked me some questions related to my academics and family background

Asked to tell 4 fav subjects

1)Electric Machines

2)Power Systems

3)Networks

4)Control Systems

 

Q)Asked to draw a integration waveform for a D.CTRAP: Integration can be possible for closed areas. Then he converted to squarewaveform

Q)Why starting current of Induction Machine is High?

Q)Why starter is required for I.M and name the types of starting Methods?

Q) Asked some questions about auto transformer starter and DOL starter?

Q)Asked to draw Torque-Speed Characteristics and plot graphs

1) What happen to torque if voltage is halved?

2)What will be load torque to start the motor comfortably? Asked to show on graph?

3) Some basic questions in Torque – speed characteristics?

Q) Gave a circuit An Ideal Current Source series to resister and capacitor asked to findvoltage

Q) Asked what is Thyristor diff between Transister and thyrister what is diode and whatis power amplifier draw characteristics of transistor …transistor swich asked to show on graph

Q) Characterisics of thyrister and turn off time value Mosfets…and some simplequestions?

Q)Asked to draw a PID controller and asked to find the transfer function and find itsstability?

Q) Asked to draw single line dia of a power system draw a long transmission lineCharging currents… if the sub conducters are used what will happen R,L,C

Q)why voltage cannot be stepped up to very high values 1000MW and above

Q)Why generating volatage is 13kv?

Q)And some basic questions related to fundamentals

                         My interview went for more than an hour. I was just sent ( did not asked me to wait) and later they told I got medical after 5 minutes.

               TIPS: Prepare all the charact and curves thoroughly concentrate on only 4 sub but deepknowledge is required…. Be strong in fundamentals they test your fundamentals. ReadStandard textbooks .. ( I have seen many reading B.L.Teraja at interview) iam not findingfault with the book but if you want to learn good concepts read standard textbooks… andimportant thing is They don’t Bother what you know you should explain it correctly.Good communication is very much required. I think this will help to the others who areaiming at DAE.Thankyou
